1. ISOFLAVONOIDES DA TRIBO DALBERGIEAE: UMA CONTRIBUIÇÃO QUIMIOSSISTEMÁTICA PARA A SUBFAMÍLIA PAPILIONOIDEAE
Plants from Fabaceae family have several secondary metabolites and high biological potential. The subfamily Papilionoideae (Fabaceae) has 28 tribes, of which Dalbergieae comprises 49 genera and 1325 species. Isoflavonoids are chemotaxonomic markers of Papilionoideae and have important biological properties. This review describes the isoflavonoids and biologi

2. Effects of organic liquid fertilizers on biological activities and fruit productivity in open-field cherry tomato
ABSTRACT This study evaluated the effects of liquid fertilizers (LF) with farm-derived renewable resources on biological activities and chemical attributes of the soil and fruit in an open-field tomato (Lycopersicon esculentum var. cerasiforme) experiment conducted in South Korea in the 2019 growing season. The LF treatments included bone+fish meal (BF), fis

3. Taxonomic study of Marsypianthes Mart. ex Benth. (Hyptidinae, Lamiaceae) in Brazil
ABSTRACT Marsypianthes is a Neotropical plant genus distributed from southern Mexico to northeastern Argentina. It is composed of six species - M. arenosa, M. burchellii, M. chamaedrys, M. foliolosa, M. hassleri, M. montana - with all occurring in Brazil except for M. arenosa, which occurs in Mexico. Marsypianthes burchellii, M. foliolosa and M. montana are

4. Fruits of neotropical species of the tribe Malveae (Malvoideae - Malvaceae): macro- and micromorphology
ABSTRACT Fruit morphology of the tribe Malveae has been discussed since the first taxonomic classifications of Malvaceae. The fruits are schizocarps, with some genera possessing an endoglossum. Besides morphological variation in the endoglossum, other differences include the number seeds per locule and ornamentation of the exocarp. An in-depth study of the f

5. Palynotaxonomy of Brazilian species of Passifloraceae sensu stricto
ABSTRACT This study aims to expand knowledge of the pollen morphology of Passifloraceae and contribute to the taxonomic delimitation of the group by morphologically characterizing pollen grains of species that occur in the Brazilian state of Bahia. Thirty-six species occur in the state, one of the genus Mitostemma (M. glaziovii) and 35 of the genus Passiflor

6. Taxonomic relevance of leaf anatomy in Banisteriopsis C.B. Rob. (Malpighiaceae)
ABSTRACT We describe the leaf anatomy of 42 of the 60 species of the genus Banisteriopsis, one of the largest and most diverse genera of Malpighiaceae in the Cerrado domain. Our aim was to identify anatomical leaf characters useful for the taxonomy and systematics of this morphological diverse genus. Expanded leaves from herbarium specimens were rehydrated a

7. Relationship between phytoplankton structure and environmental variables in tropical reservoirs with different trophic states
ABSTRACT Phytoplankton structure is influenced by environmental factors, seasonal cycles and the trophic state of the system. The objective of the present study was to identify guilds of phytoplankton species that are representative of seasonality and trophic status. We evaluated phytoplankton biomass and species composition in five tropical reservoirs, with

8. Population dynamics and description of larva and pupa of Cyclocephala tucumana Bréthes, 1904 in West-Central Brazil, and remarks on immatures of other Cyclocephala species (Coleoptera: Scarabaeidae: Dynastinae)
ABSTRACT Some species of Cyclocephala Dejean, 1821 (Coleoptera, Scarabaeidae, Dynastinae, Cyclocephalini) were reported as crop or pasture pests. Within this genus, Cyclocephla tucumana Bréthes, 1904 was noticed in cultivated areas in South Brazil, 2009 − 2010. Other study found larvae of the species associated with pastures in Aquidauana, Mato Grasso do

9. A tribo Dalbergieae s.l. (Leguminosae-Papilionoideae) no município de Caetité, Bahia, Brasil
Resumo Dalbergieae s.l. possui 49 gêneros e 1.324 espécies distribuídas principalmente na região neotropical. No Brasil está representada por 380 espécies e 18 gêneros. Estudos florísticos/taxonômicos sobre as Dalbergieae no Brasil são pontuais, o conhecimento sobre a sua diversidade ainda é fragmentado ou encontra-se desatualizado. Com relação

11. O gênero Polystachya (Orchidaceae, Polystachyinae) no estado do Paraná, Brasil
Resumo Polystachya compreende cerca de 200 espécies epífitas e terrestres, com distribuição Pantropical. As espécies do gênero destacam-se pois nem o pedúnculo e nem o ovário ressupinam, de modo que o labelo está posicionado na parte superior da flor. O objetivo deste estudo foi realizar o tratamento taxonômico de Polystachya no estado do Paraná,

12. O gênero Bulbophyllum Thouars (Orchidaceae, Epidendroideae) no Parque Nacional da Chapada dos Veadeiros, Goiás, Brasil
RESUMO Bulbophyllum é um dos maiores gêneros de Angiospermas, com 2.200 espécies em todo o mundo. No Brasil ocorrem 60 espécies, das quais 10 são registradas para o estado de Goiás. Diante da carência de estudos taxonômicos sobre este gênero no Domínio Fitogeográfico do Cerrado (DFC), objetivou-se estudá-lo no Parque Nacional da Chapada dos Veade
